Embodiment Construction

[0034] The present invention is based on the discovery of a laminated multilayer film structure having utility as a gas barrier film, as useful in the fabrication of a wide variety of end-use articles, including, without limitation, gastric occlusion devices.

[0035] Thus, while the invention is described more fully hereinafter with reference to an illustrative gastric occlusive device, as fabricated from the laminated multilayer film of the invention, it will be appreciated that the inventive film is susceptible of a wide variety of usages, e.g., in applications in which the film must contain a gas at pressure at least equal to pressure of an ambient environment of the article incorporating such film, or in which permeation of gas through the film would adversely affect a structure, article or material on an opposite side of the barrier film from such gas.

[0036] The gas barrier film structure of the invention is a laminate including: [0037] a layer of sealing film, having main top ...

Abstract

A method of treating a patient comprises: introducing to a physiological locus of said patient a balloon formed from two vacuum thermoformed half-sections of a multilayer film a layer of sealing film and at least one layer of thermoplastic polymer film, wherein the vacuum thermoformed half-sections are bonded together; and the balloon includes an inflation element (such as a self-healing valve and / or an effervescent material) adapted to permit inflation of the balloon at the physiological locus with a fluid.

Description

STATEMENT OF RELATED APPLICATION(S) [0001] This application is a continuation of an claims benefit of U.S. patent application Ser. No. 10 / 815,282, filed on Apr. 1, 2004 and entitled “EXTRUSION LAMINATE POLYMERIC FILM ARTICLE AND GASTRIC OCCLUSIVE DEVICE COMPRISING SAME.”BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to therapeutic intervention methods, such as gastric occlusion methods, employing implantable balloon structures formed of laminate films, and to related therapeutic devices. [0004] 2. Description of the Related Art [0005] In the field of polymeric film technology, involving polymeric sheet stock or web-form material, typically having a thickness of less than about 25 mils, there is a need for gas-barrier films. [0006] Such gas barrier films may be employed for containment of a specific gas when used to form gas receptacles, or as a packaging, cushioning or preservative structure (e.g., when fabricated to contain gas species su...
